Title: Method and device for cutting optical fiber
Inventor: TANAKA TOSHIYASU
IPC: B26D3/16
Filed: 1986-12-30
Abstract: PURPOSE:To smoothly and easily cut a section by forming a cut around an optical fiber strand while applying a tension to the optical fiber strand to cut the optical fiber strand. CONSTITUTION:An optical fiber strand 60 is kept in the tension applied state by the first coiled spring 32. When a cutting member 22 is moved left, the fiber strand 60 is interposed between cutting edges 62 of two cutters 50 to form cuts on the outside of the fiber strand 60. Since the tension is applied to the fiber strand 60, the fiber strand 60 is cut with minimum cuts. In the case of cutting, cutters 60 are turned with pins 46 as fulcrums to be free. Thus, cutters 50 are uniformly brought into contact with the fiber strand 60 to avoid the unevenness of cutting due to the off-center state, and a uniform and satisfactory section is obtained.

Abstract: PURPOSE:To make a magnetic sensor or a temperature sensor usable even in a region under the effect of a magnetic field and thereby to enable measurement of a weak magnetic field by obtaining the sensor by joining a metal of an ordinary conductor to an oxide superconductor. CONSTITUTION:A metal 2 of an ordinary conductor is joined to an oxide superconductor 1 to form a joint part 3 of the superconductor 1 and the metal 2, and this joint part 3 is used as a magnetism sensing element or a temperature sensing element. In the case when a change in the resistance of the joint part 3 of the superconductor 1 and the metal 2 due to temperature shows a metallic behavior, the resistance of the joint part 3 is sensitive to magnetism in a region of the critical temperature of the superconductor 1 or below and changes. By keeping the temperature of the joint part 3 at the critical temperature or below, therefore, the joint part 3 can be used as the magnetism sensing element. In the case when the change in the resistance of the joint part 3 due to temperature shows a behavior of a semiconductor, the resistance of the joint part 3 is not sensitive to the magnetism, but is sensitive only to the temperature and changes in a region of the critical temperature of the superconductor 1 or below and a region above the critical temperature. Accordingly, the joint part 3 can be used as the temperature sensing element.
